Baidu’s autonomous cars have driven more than 1 million miles across 13 cities in China

Today at Baidu’s annual Create AI developer conference in Beijing, the China-based search giant announced a slew of updates across its ever-expanding driverless car ecosystem. They come as analysts at Research and Markets forecast there will be some 20 million autonomous and semiautonomous cars in operation in the U.S. by 2030, up from millions today.

Baidu revealed that its fleet of 300 level vehicles across 13 cities recently achieved a major milestone: 2 million kilometers (1.2 million miles) driven autonomously in urban environments. (The Society of Automotive Engineers defines level 4 as systems that can operate safely without oversight in select conditions.) In related news, the Beijing Municipal Commission of Transport allocated its entire first batch of T4 autonomous driving test permits to Baidu earlier this month.
